Despite looking like an old potato, Jatropha berlandieri is in the euphorbia family.
This Jathropha is medium and a perfect conversation piece.
It is a caudiciform plant adapted to prolonged periods of drought it can store water and survive many months without rain.
Jatropha berlandieri grows from an enlarged, tuberlike woody caudex. It is deciduous, losing both stems and leaves, and spends the winter dormant. The large caudex is globe-shaped, tan-white, and can grow up to 8 inches wide and 12 inches tall, or more.
